[BUG] HDA Intel PCH, HDMI , HDA Intel PCH, ALC886 Digital, no IEC958 / HDMI output/passthrough to AVR
ALSA versions 1.0.28
Kernel Driver versions 3.12.40
Partly FIXED in Longterm Stable Kernel 4.19.324 and using HDMI DEV 1 instead of 0.
2 CH PCM HDMI to AVR works now but AC3/DTS passthrough still not or is not recognized by AVR or some wrong AES setting but iec958 optical out AC3/DTS output to AVR works.
New BUG: No more 5.1 Analog Output on the CM106 USB Box if AC3 stream is selected.

Software crosscheck with CM106 USB Soundbox iec958: works OK.
Where to start in the drivers source code to fix it?
